Dianthus plant named ‘KonD1014K3’

ABSTRACT

A new and distinct cultivar of  Dianthus  plant named ‘KonD1014K3’, characterized by its compact, uniformly mounding and upright to somewhat outwardly spreading plant habit; dense and bushy appearance; dark green-colored leaves; freely and remontant flowering habit; light red purple-colored double flowers; vernalization treatment is not required for flowering; and good container and garden performance.

Botanical designation: Dianthus hybrida.

Cultivar denomination: ‘KonD1014K3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dianthus plant, botanically known as Dianthus hybrida, grown commercially as a container and garden plant and hereinafter referred to by the name ‘KonD1014K3’.

The new Dianthus plant is a product of a planned breeding program conducted by the Inventor in Westerbrok, The Netherlands. The objective of the breeding program is to create new hardy Dianthus plants with remontant flowering habit with good container and garden performance.

The new Dianthus plant originated from a cross-pollination in May, 2009 of a proprietary selection of Dianthus hybrida identified as code number Ut95, not patented, as the female, or seed, parent with a proprietary selection of Dianthus hybrida identified as code number D900, not patented, as the male, or pollen, plant. The new Dianthus plant was discovered and selected by the Inventor in July, 2010 as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Westerbrok, The Netherlands.

Asexual reproduction of the new Dianthus plant by vegetive terminal cuttings propagated in a controlled greenhouse environment in Chicago, Ill. since September, 2010 has shown that the unique features of this new Dianthus plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Dianthus have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KonD1014K3’. These characteristics in combination distinguish ‘KonD1014K3’ as a new and distinct Dianthus plant:

-   -   1. Compact, uniformly mounding and upright to somewhat outwardly         spreading plant habit; dense and bushy appearance.     -   2. Dark green-colored leaves.     -   3. Freely and remontant flowering habit.     -   4. Light red purple-colored double flowers.     -   5. No vernalization requirement for flowering.     -   6. Good container and garden performance.

Plants of the new Dianthus differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Dianthus are darker green than         leaves of plants of the female parent selection.     -   2. Plants of the new Dianthus have larger flowers than plants of         the female parent selection.     -   3. Plants of the new Dianthus flower for a longer period of time         than plants of the female parent selection.

Plants of the new Dianthus differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Dianthus are not as vigorous as plants of         the male parent selection.     -   2. Plants of the new Dianthus and the male parent selection         differ in flower type as plants of the male parent selection         have single-type flowers.

Plants of the new Dianthus can also be compared to plants of Dianthus caryophyllus ‘Kahori’, not patented. In side-by-side comparisons, plants of the new Dianthus differ primarily from plants of ‘Kahori’ in the following characteristics:

-   -   1. Plants of the new Dianthus are more uniform than plants of         ‘Kahori’.     -   2. Plants of the new Dianthus and ‘Kahori’ differ in flower type         as plants of ‘Kahori’ have single-type flowers.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the winter and spring in one-gallon containers in a glass-covered greenhouse in Elburn, Ill. and under cultural practices typical of commercial container Dianthus production. During the final production phase of the plants, day temperatures ranged from 18° C. to 21° C. and night temperatures ranged from 13° C. to 16° C. Plants were pinched two times during the propagation phase and were eight months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
